The Inland TN470 is a solid-state drive in the M.2 2280 form factor, launched in 2024. It is available in capacities ranging from 1 TB to 2 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Inland TN470 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5027-E27T from Phison, a DRAM cache is not available. Inland has installed 162-layer TLC NAND flash on the TN470, the flash chips are made by Toshiba. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The cache is sized at 50 GB, once it is full, writes complete at 800 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The TN470 is rated for sequential read speeds of up to 7,300 MB/s and 6,100 MB/s write; random IO reaches 900K IOPS for read and 800K for writes.
At its launch, the SSD was priced at 80 USD. The warranty length is set to 6 years, which is a very long warranty, better than most other drives on the market. Inland guarantees an endurance rating of 600 TBW, a relatively low value compared to other SSDs.
